Samsung Electronics has carried out one of its most significant leadership changes in recent years, elevating mobile boss TM Roh into an even more powerful role at the heart of the company. In the new structure, Roh becomes head of the Device eXperience Division, the unit that brings together smartphones, tablets, TVs, displays, appliances and many of the products ordinary consumers associate with the Samsung name. 
On top of that, he has been appointed co chief executive of Samsung Electronics, a promotion that underlines how central the consumer and mobile business has become to the groups global strategy.
Roh will share the top job with Young Hyun Jun, vice chairman and long time head of the Device Solutions Division. That side of the company controls Samsungs enormous memory, storage and semiconductor operations, which supply components not only to Samsungs own products but also to many of its rivals. The co CEO system is not new for Samsung, but this particular pairing sends a clear signal: one leader is squarely focused on components and infrastructure, while the other is charged with turning those technologies into polished experiences that consumers can actually hold in their hands.
Crucially, Roh is not stepping away from the mobile business that made him a familiar name to industry watchers. He will continue to lead the Mobile eXperience business, the division that designs and markets Galaxy flagships, foldable phones, mid range devices, tablets, wearables and a growing family of connected accessories. Under his watch, Samsung has defended its place near the top of the global smartphone market, pushed foldable form factors closer to the mainstream and leaned heavily into camera innovation, ecosystem features and long term software support. The decision to give him a broader mandate suggests that the board views this performance as a template for the rest of the consumer portfolio.
Bringing the wider Device eXperience portfolio under Roh creates a single point of accountability for nearly everything a typical household might plug into a wall and connect to Wi Fi. The DX Division spans televisions, monitors, smart home devices, audio products, home appliances and more. Aligning all of those categories with the same leadership and the same design philosophy should make it easier for Samsung to deliver a coherent user journey, from the moment a buyer unboxes a new phone to the way that phone talks to the television, washing machine or robot vacuum in the next room. In a world where ecosystems often matter more than any single gadget, that kind of consistency has become a competitive requirement rather than a simple extra.
The reshuffle is not only about the co CEO roles. Samsung has also appointed Janghyun Yoon as president and chief technology officer for the Device eXperience Division, placing him in charge of Samsung Research, the global network of labs that work on long term projects. Yoon previously led Samsung Venture Investment, where he spent years scanning the startup landscape for breakthrough ideas in software, artificial intelligence, connectivity and platforms. Before that, he oversaw software platforms, internet of things initiatives and Tizen development inside the mobile business. That mix of hands on engineering and investment oversight gives him a rare vantage point on which technologies are ready for prime time and which ones still need years of careful nurturing.
In parallel, the company has named Hongkun Park as head of the Samsung Advanced Institute of Technology, the group often described as the companys in house think tank for future hardware. Park is a professor at Harvard University and a respected figure in nanoscience, quantum science and engineering. His appointment reinforces the idea that Samsung wants a tighter loop between blue sky research and commercial products. Discoveries in quantum materials or nanoscale fabrication do not stay in academic journals for long when a company the size of Samsung is searching for ways to build faster memory, more efficient processors or entirely new display technologies.
Viewed together, these moves amount to a rewiring of the pipeline that runs from physics labs to factory floors and eventually to store shelves. TM Roh is positioned as the executive who turns advanced components and research into consumer ready experiences. Janghyun Yoon is tasked with ensuring that platforms, interfaces and software make those experiences intuitive and sticky. Hongkun Park is charged with making sure that Samsung does not miss the next wave in areas such as quantum computing, advanced sensors or novel materials. At a time when every major tech brand is racing to redefine itself around artificial intelligence, this trio is meant to guarantee that Samsung can marry deep scientific know how with devices that feel smart, responsive and genuinely helpful.
For customers and competitors alike, the message is straightforward. Samsung wants to move faster, close the gap between ideas and products and present a more unified face to the world across phones, televisions and appliances. Elevating TM Roh to co CEO status while keeping him in control of the mobile portfolio shows confidence in his track record and hints that the Galaxy playbook of tight integration and relentless iteration will spread across the whole consumer ecosystem. The real impact of this leadership shuffle will be measured over the coming years, but one thing is already clear: Samsung has placed some of its most experienced and forward looking minds in positions where they can shape the companys next decade.
